" LIQUID-COOLING .D EvIcE.

Application led September The invention relates to liquid cooling devices of the internalor double tube type, and more particularly to the heads forming the elbow connections between the tubes.

Such coolerscomprise tiers-of horizontal double spaced tubes, the ends ofthe inner and outer tubes respectively being connected for the How of liquid successively through the tubes of the tier. The use of such coolers 1n the treatment of milk in dairy plants necessitates a construction permitting ready access to all surfaces in contact with the milk for cleaning and sterilization after use.

, An object of the present invention is to provide an improved construction of the heads connecting the tube ends wherein simple arrangement,'few parts, and adaptabihty to easy assembling and disassembling is attained. Another object is to provide "1 means for preventing any leakage'or lby- A passing ofthe liquid between the passages of a'preferred embodiment of t liquid tightjoint.

provided with a pair of 'openings 12 and 13V connecting theinner tubes and the passages .connecting the outer tubes.

Qther objects will be apparentin the following description e invention.

Referring to the drawings, Fig.. 1 is a plan view of one of the heads, and Fig. 2 anend view of the same. Fig. 3 is a sectional ele- -vation of the head and. fractional parts of the tubes to which it is connected, andFig.

4 is an end view of the head with the cover orcap removed. Fig. 5 is a sectional viewof the leakage-preventing packing ring.

Referring to the drawings, thenumeral 1 vinidicates the base element 4of the head construction, which is provided with a pair of rearwardly extending annular anges 2 and 3, within which are secured a pair of outer tubes 4 and A5, the base 1 having openings 6 and 7 for communication from the tubes 4 and 5 with a chamber 8',formed bya for-v through which pass a pair of inner tubes. 14 and 15 having a slidable bearingin the openings.' The openings 12 and 13 are positioned' to support the inner tubesin spaced relation to the outer tubes 4 and 5.

outerv plate 16 is supported on the 29, 1926. Serial No. 138,367.

inner tubes 14 and 15, and is provided with openinfrs 17 and 18 through which-pass the ends o. the inner tubes.

The inner plate l and the outer plate 16 i are preferably spaced one from the other,

andare provided with recesses 19, 20,21and 22 in their proximate faces in the marginal v l openings through to receive resilient packing, and. yalso `the' y rings 23 and 24 loosely positioned about each of the inner tubes.V The rings 23 and 24 opthe recesses into liquid-tight contact with the inner tubes .1 4 and 15 when the outer plate 16 is forced inwardly'toward the inner plate 10.

Each of the rings 23 and 24 is constructed with an annular recess 25 formed in its inner surface (see Fig. 5)' from which one or more outlets 26 open outwardly'through the ring. In the case of any failure in the packing about the tubes caused thereby would be intercepted by the recesses 25 and escape through the outlets 26,'thuspreventing the intermixture of the liquid flowing in the tubes 4 and 5 with that in the tubes `14 and 15. The voutward escape of the leakage also gives visible warning of the fact that the packing is leaking, and enables'immediate correction.y i

The outer plate 16 is` also provided in its front face with a peripheral recess 27 adapt- 'I ed to -receive packing material and within which is supported a flange 28 formed on the inner ce of a cover cap 29, the cap 29 being sha'p d to provide a chamber 30 between it and-t e outer plate 16 for communication. betwee the inner tubes 14 and 15 extending thro gh the openings in the outer plate'16.

The' cap '29 is preferably supported by ia verate to compress the resilient materialV in 14 and 15, any leakage pair of lugs 31 pivotally supported on a lever '32, which latter is pivoted on a swinging support 33 hinged on the lbasel asv indicated at 34. The free vendof the lever 32 is referably slotted-to receivethe swinging 1t 35 oppositely hinged. onthe base 1 and carry- .ing a thumb nut '36 bearing outwardly upon the `lever 32-and`clamping the separable parts of the .headstructu're in assembled relation.`

In operatiomthej Huid passing betweenthe inner 'and outer tubes14 and. 4 of the upper .-of the tier of tubes, as illustrated in Fig. 3,

flows through 'the'chamber 8 and into thespace between the outer and inner tubes of the lower pair. The liquid flowing through the upper tube 14, of the inner tubes illustrated in Fig. 3, passes through the chamber 30, formed by the cap, and into the lower of 'the 'inner'tubes lVith the parts of the head structure assembled as described, it will be seen that there is no possibility of intermixing the fluid ilovving in the outer tubes with that of the fluid flowing in the inner tubes. i' To disassemble the head structure for cleaning, releasing the thumb nut 36 and swinging away the lever 32 with its supported capl 29, permits the ready removal of the inner and outer plates 10 vand 16, after which the inner tubes may be Withdrawn, and all surfaces of. both tubes and head structure with which the fluid is in contact are f readily accessible for cleaning and sterilization.
